Eliminating Arbitrary Constant, 7

Category: Differential Equations 

"Published in Newark, California, USA"

Eliminate the arbitrary constant for


ω is a parameter.

Solution:

Consider the given equation above  


Take the derivative on both sides of the equation with respect to t, we have 





Take the derivative on both sides of the equation again with respect to t, we have  





Multiply the given equation by ω², we have




Now, let's consider the two equations



If you add the two equations, their right side will be eliminated and therefore, the final answer is
